Working around discomfort

Modifications by body area

How Handler adjusts the hamstring floss when a lifter reports a sensitive area. These are training modifications, not treatment. Pain that persists or worsens needs clinical assessment.

Hip
Use a comfortable stance and shorten the range if the front of the hip pinches.
Lower back
Reduce load, brace before each rep, and stop if you cannot keep a neutral spine.
Knee
Shorten the range, keep the knee tracking over the toes, and use a controlled tempo.
